Water pollution has become one of the most concerned issues in society. A large amount of sewage discharge has further damaged the water environment, especially some chemical companies, where sewage is directly discharged into the river without treatment, which seriously damages the environment and affects people's production and life. The existing sewage treatment stations are all arranged in places far away from the urban area, and the location is relatively fixed. Sewage needs to be transported to the sewage treatment station through sewage pipes. The transportation path is long and the sewage treatment efficiency is very low. When treating sewage in some remote areas, it is often not effectively solved and can only discharge sewage to the ground, wasting water resources. The existing containerized sewage treatment device only has a filtering effect, and the filter residue sludge produced by the filtration needs to be cleaned manually, which has the defect of inconvenience in use. Summary of the invention

[0003] In order to solve the defects of the prior art, the present invention provides a novel container vertical fiber filter cloth filter tank.

[0014] As a preferred technical solution of the present invention, the sewage treatment method of the novel container vertical fiber filter cloth filter tank is to inject sewage into the filter tank through the water inlet pipe, and the sewage, under the action of its own gravity, passes through the vertical fiber filter cloth of the filter system to the inner cavity of the filter system, and then the filtered water flows out from the outlet pipe. In this process, when a large amount of filter residue and sludge are attached to the vertical fiber filter cloth, the filtration efficiency of the vertical fiber filter cloth is reduced, which will cause the liquid level to rise. The liquid level is detected by the liquid level sensor, and when the liquid level reaches the cleaning value, the fixed drive motor drives the active trolley to perform linear reciprocating motion left and right through the sprocket, and the active trolley drives the mobile trolley to perform linear reciprocating motion through the traction rope. The suction force generated by the fixed backwashing pump is used to drive the sludge suction branch pipe to perform linear reciprocating motion along the filter system as the mobile trolley drives the sludge suction branch pipe to perform linear reciprocating motion along the filter system, and the filter system is backwashed to achieve the cleaning of the filter residue and sludge on the surface of the filter system, until the liquid level meter detects that the water level has reached a safe value, and then the cleaning work is stopped.

It is smaller in size than the traditional sewage filtration system, which is convenient for transferring and carrying the box body. At the same time, it is easy to load into the container, which is convenient for long-distance transportation. The sewage treatment method of the container vertical fiber filter cloth filter tank is to inject sewage into the filter tank through the water inlet pipe. Under the action of its own gravity, the sewage passes through the vertical fiber filter cloth of the filtration system to the inner cavity of the filtration system, and then the filtered water flows out from the outlet pipe. The suction force generated by the fixed backwashing pump is used. As the mobile trolley drives the sludge suction branch pipe to move back and forth in a straight line along the filtration system, the filtration system is backwashed to clean the filter residue and sludge on the surface of the filtration system. After the liquid level meter detects that the water level has reached a safe value, the cleaning work is stopped. This has a good self-cleaning ability.

[0017] 2. This type of container vertical fiber filter cloth filter tank drives the active trolley to perform left and right linear reciprocating motion through a fixed drive motor through a sprocket, and the active trolley drives the mobile trolley to perform linear reciprocating motion through a traction rope.
